Softube Tube-tech Pe 1c V2.5.9 -win- Jun 2026

In the world of professional audio, few pieces of outboard hardware command as much respect as the Tube-Tech PE 1C. This Danish passive equalizer has graced the mastering suites and tracking chains of countless hit records since the 1980s. Its legendary status is built on a foundation of musical curves, silky top-end air, and a solid, punchy low-end that is nearly impossible to replicate with digital algorithms—until now.

Softube redesigned the harmonic distortion algorithm in the output stage. The "Drive" control now responds more dynamically to transient peaks. At lower gains, the THD (Total Harmonic Distortion) is nearly non-existent. At higher gains, the plugin introduces even-order harmonics typical of Class A tube circuits, without harsh digital clipping. Softube Tube-Tech PE 1C v2.5.9 -WiN-
